class_docstr: The G2P model evaluation wrapper
  
  Arguments
  ---------
  hparams: dict
      the dictionary from a parsed hyperparameter file
  device: str
      the device identifier
  model_state: dict
      a pre-loaded model state for a "warm start" if applicable
      - could be useful if hyperparameters have changed, but
      the same model can be reused from one run to the next
